Performance enhancement of natural asphalt using waste-derived modifiers: Sugarcane molasses and waste engine oil
...Show More Authors

The growing demand for sustainable and high-performance asphalt binders has prompted the exploration of waste-derived modifiers. This study investigates the performance enhancement of Natural Asphalt (NA) using Sugarcane Molasses (SM) and Waste Engine Oil (WEO). The modified blends were prepared by partially replacing 50 % NA with varying proportions of SM and WEO ranging from 10 % to 40 % of the total weight of NA. Comprehensive testing was conducted, including penetration, softening point, ductility, viscosity, Bending Beam Rheometer (BBR), Multiple Stress Creep Recovery (MSCR), Energy Dispersive X-ray Spectroscopy (EDX), Fourier Transform Infrared (FTIR) spectroscopy, and Scanning Electron Microscopy (SEM). The results demonstrated that modified blends with a high WEO content significantly increased fluidity, reducing rotational viscosity by up to 91 % for the blend with 40 % WEO and 10 % SM at 135 ◦C. Conversely, higher SM content increased stiffness, as seen in the blend with 40 % SM and 10 % WEO, with penetration values rising by 305 % compared to unmodified NA. Rheological testing showed that the 40 % SM and 10 % WEO blend achieved the highest rutting resistance with a Performance Grade (PG) of 88 ◦C, while the 40 % WEO and 10 % SM blend exhibited the best fatigue resistance with a 55 % reduction in G* .sinδ. Low-temperature performance was significantly improved across all blends, with the 40 % WEO and 10 % SM blend achieving the lowest creep stiffness and highest m-value, ensuring superior thermal cracking resistance. Chemical analysis revealed increased oxygen content (18.6 %) and reduced sulfur content (60 %) in the 40 % SM and 10 % WEO blend, indicating enhanced oxidation resistance. SEM analysis confirmed the development of dense morphology in the 40 % SM and 10 % WEO blend, correlating with superior structural integrity. Grey decision analysis identified the 40 % SM and 10 % WEO blend as the optimal blend with the lowest bull’s-eye distance, reflecting balanced performance across all parameters. These findings highlight the complementary effects of SM and WEO in enhancing the performance of NA, with the 40 % SM and 10 % WEO blend emerging as the most promising blend for bio-asphalt applications.

Prediction of Hydraulic Flow Units for Jeribe Reservoir in Jambour Oil Field Applying Flow Zone Indicator Method
...Show More Authors

The Jeribe reservoir in the Jambour Oil Field is a complex and heterogeneous carbonate reservoir characterized by a wide range of permeability variations. Due to limited availability of core plugs in most wells, it becomes crucial to establish correlations between cored wells and apply them to uncored wells for predicting permeability. In recent years, the Flow Zone Indicator (FZI) approach has gained significant applicability for predicting hydraulic flow units (HFUs) and identifying rock types within the reservoir units.    This paper aims to develop a permeability model based on the principles of the Flow Zone Indicator. Analysis of core permeability versus core porosity plot and Reservoir Quality Index (RQI) - Normalized poros

Development of 1D-Synthetic Geomechanical Well Logs for Applications Related to Reservoir Geomechanics in Buzurgan Oil Field
...Show More Authors

Knowledge of the distribution of the rock mechanical properties along the depth of the wells is an important task for many applications related to reservoir geomechanics. Such these applications are wellbore stability analysis, hydraulic fracturing, reservoir compaction and subsidence, sand production, and fault reactivation. A major challenge with determining the rock mechanical properties is that they are not directly measured at the wellbore. They can be only sampled at well location using rock testing. Furthermore, the core analysis provides discrete data measurements for specific depth as well as it is often available only for a few wells in a field of interest. This study presents a methodology to generate synthetic-geomechani

Evaluation of Machine Learning Techniques for Missing Well Log Data in Buzurgan Oil Field: A Case Study
...Show More Authors

The investigation of machine learning techniques for addressing missing well-log data has garnered considerable interest recently, especially as the oil and gas sector pursues novel approaches to improve data interpretation and reservoir characterization. Conversely, for wells that have been in operation for several years, conventional measurement techniques frequently encounter challenges related to availability, including the lack of well-log data, cost considerations, and precision issues. This study's objective is to enhance reservoir characterization by automating well-log creation using machine-learning techniques. Among the methods are multi-resolution graph-based clustering and the similarity threshold method. By using cutti

Biostratigraphy of the Late Cretaceous-Early Paleocene Succession in Selected Wells, Jambur Oil field, Kirkuk, Northern Iraq
...Show More Authors

The Late Cretaceous-Early Paleocene Shiranish and Aliji formations have been studied in three selected wells in Jambur Oil Field (Ja-50, Ja-53, and Ja-67) in Kirkuk, Northeastern Iraq. This study included lithostratigraphy and biostratigraphy. The Late Campanian-Maastrichtian Shiranish Formation consist mainly of thin marly and chalky limestone beds overlain by thin marl beds, with some beds of marly limestone representing an outer shelf basinal environment, the unconformable contact with the above Middle Paleocene-Early Eocene Aliji Formation contain layers of limestone with marly limestone and chalky limestone which represents an outer shelf basinal environment. Five Biozones in the Shiranish Formation were determined which are: 1
